Could someone post something about vaporizing plain leaf or extract? SWIM believed the vape point is around 530F....
I don't want to out of good common sense... it's very easy to take a stupid amount of Salvinorin A, very quickly, when vaping...
but, your best bet is to take around 7mg of crude Salvinorin A powder, place it in an aluminum votive candle dish, and heat the bottom side of the dish up quickly with a butane lighter...
